Some videos on the ATC YouTube channel have chapters—timestamps—that I have added for different topics. I haven’t done that for all the videos, but it is really cool that YouTube has identified some of the topics and added the timestamps automatically.

I spent a couple hours today collecting total organic material (OM246) samples and soil nutrient samples. When this Tifeagle bermudagrass green was tested for total organic material twelve months ago, the OM2 (total organic material in the top 2 cm) was 11.

Have you heard about the Park Grass experiment? The one that started in 1856 with different fertilizer treatments applied to a hay meadow in England, with those fertilizer treatments applied year after year to see what happened to hay yields?

This topic—carbon in turfgrass soils—was the subject of a Frankly Speaking podcast episode. One of the topics host Frank Rossi spoke about with guests Drs. Claire Phillips and Alec Kowalewski was the nitrogen mineralized from soil organic matter.

First some background information. I had shared this post that showed a number of different scenarios of organic matter change with hollow-tine cultivation (coring) and solid-tine cultivation, including examples with and without sand topdressing.

I recommend annual soil testing of professionally-managed turfgrass grown on sand rootzones. For turf growing in soil, I don’t mind testing every two or three years. But sand rootzones usually aren’t very well buffered and important soil properties can change rapidly.

After I wrote this post about the differences in P fertilizer recommendations when using different methods for soil test interpretation, I heard from some readers that it seemed I was taking something simple—MLSN—and making it seem complicated.

The first time I went to Spain, I was a university student. I remember taking a bus out to the general vicinity of El Saler, walking to the club entrance, asking if I could meet the greenkeeper, and then being lucky enough to have that answer be yes.

On November 2 & 3, I’ll be at the Portuguese Greenkeepers Conference in Porto. You can register for the conference at the APG website. Here are three quick notes. 1. The five exciting topics I’ll be discussing I’m going to lead a series of short seminars at the conference.

Daniel Hahn and Romain Giraud wrote an article on LinkedIn about fertilisation decisions based on MLSN and STERF’s precision fertilisation (SPF). If you are at all interested in this topic, I hope you’ll read their article.
